BOSTON — Midway through the Bruins’ 5-2 rookie game win over the New York Islanders at TD Garden, center Joe Colborne was helped off the ice and left a pool of blood back on the ice. He did not return to the game.

After the game, Bruins general manager Peter Chiarelli said that Colborne suffered a broken nose and a chipped tooth and would go to the hospital for evaluation. He’s likely unavailable for the second rookie game Thursday night.

“He was in good spirits actually, so I think he’ll be OK,” said Chiarelli.

The GM said he hadn’t seen the replay but heard that it might’ve been a teammates’ stick that fell Colborne. After the play, Isles rookie Justin Dibenedetto was assessed a five-minute major for elbowing and a game misconduct.
